ABSTRACT:
Latin name of the genus and species of the plant claimed:
Euphorbia pulcherrima.
Variety denomination: Fiselfi Pink.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of poinsettia plant known by the variety denomination ‘Fiselfi Pink’, and botanicallyknown as
Euphorbia pulcherrima.
‘Fiselfi Pink’ was derived from a naturally occurring mutation in the variety ‘Fiselfi’ (U.S. Plant Pat. No. 13,736). ‘Fiselfi’ is characterized by bright red colored, pointed bracts, dark-green foliage with distinct lobes, and relatively compact plant habit.
The mutation was discovered by Andrea Moes, the inventor, in a greenhouse in Dorsten, Germany, in November, 2000, where among a group of flowering branched plants, a partly pink colored plant was found. The plant was taken to Hillscheid, Germany, and was left to develop vegetative shoots. Cuttings from the mutated branched were used for vegetative propagation in the first act of asexual reproduction, in the spring of 2001. The resulting plants appeared uniform, and the pink bract color was stable. This result was confirmed when the propagation and examination was repeated on a larger scale in the fall of 2002.
Horticultural examination of the clone starting in 2001 and continuing thereafter has demonstrated that the combination of characteristics as herein disclosed for ‘Fiselfi Pink’ are firmly fixed and retained through successive generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Fiselfi Pink’, which in combination distinguish this Poinsettia as a new and distinct cultivar:
1. bright pink colored, pointed bracts;
2. medium sized, star-shaped inflorescence;
3. uniform dark-green foliage with distinct lobes;
4. compact and round, well-branched plant habit; and
5. early flowering response.
‘Fiselfi Pink’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day-length. The following observations, measurements and comparisons describe plants grown in Hillscheid, Germany, under greenhouse conditions which approximate those generally used in commercial practice.
Of the many commercial cultivars known to the inventor, the most similar in comparison to ‘Fiselfi Pink’ is the parental cultivar ‘Fiselfi’, and the comparison cultivar ‘Fissonosa’ (U.S. Plant Pat. No. 10,182).
In contrast to the red colored bracts of ‘Fiselfi’, ‘Fiselfi Pink’ has pink colored bracts, a somewhat smaller plant habit, and slightly less distinct expression of lobes of bracts and leaves.
In comparison to ‘Fissonosa’, ‘Fiselfi Pink’ has a somewhat deeper and more uniform tone of bract color (a relatively little difference of color between older and younger bracts), and the bract aspect is somewhat upward directed, while the bract aspect of ‘Fissonosa’ is horizontal or directed slightly downward. Furthermore, the plant habit of ‘Fiselfi pink’ is more compact, and plants are generally more tolerant to low temperature during cultivation.
